Title: Audio unit mounting on car
Inventor: KOBASHI MAKOTO
IPC: H03G5/16
Filed: 1979-05-07
Abstract: PURPOSE: To perform automatic adjustment of sound volume and quality depending on the amplitude of noise with a simple circuit constitution, by picking up only the component of specific frequency band of noise for control signal.  
     CONSTITUTION: The time constant circuit 33 determining the response speed in sound volume change consists of the resistors R 331 , R 332  and capacitor C 331 , and the time constant τ is set to 1∼5 seconds. The control signal from the circuit 33 changes with the band noise passed through the filter 31 which blocks the frequency components about 20Hz or less and passes the frequency components more than those. This control signal is fed to the gate of FETTr42 being the sound volume connected to the emitter of the amplifying transistor Tr41 in the audio signal reproducing circuit 4 in AC. Since Tr42 produces the resistance change between the source and drain depending on the level fed with the control signal, the amplifying factor of Tr41 changes with it. Accordingly, the sound volume adjustment can automatically be made depending on the noise and the driver can enjoy the listening signal safely.
